I use something similar here.  I run find on specific directories and
use the -x option though with -mtime:

	# make installworld
	# find / -x -mtime 1h > /tmp/files.root
	# find /var -x -mtime 1h > /tmp/files.var
	# find /usr -x -mtime 1h > /tmp/files.var

Then I manually skim through the lists and see if I want to keep
something listed in there.  Eventually, I delete the obsolete files
with something like:

	# for filelist in /tmp/files.* ;do
	      xargs chflags noschg < ${filelist}
	      xargs rm -fr < ${filelist}
	  done
